Deuteronomy 32:16-18

ASV(i) 16 They moved him to jealousy with strange [gods];
With abominations provoked they him to anger. 17 They sacrificed unto demons, [which were] no God,
To gods that they knew not,
To new [gods] that came up of late,
Which your fathers dreaded not. 18 Of the Rock that begat thee thou art unmindful,
And hast forgotten God that gave thee birth.
